the directx.c edit has more to do with character models than avoiding a fatal crash, but you could give it a shot (takes literally 2 hours to compile tho). I've ran it both with and without compiling wine from source, but have had my own unresolved
issues as well.
If you, instead of clicking the script, just open a terminal and copy/paste the 2 commands into it, you should be able to paste the logs of wine's output (it won't like auto-close the terminal when it crashes... or at least shouldnt !) and then it'll be easier to diagnose where its going haywire.
